(aws-ecs-patterns): desiredTaskCount not a property of aws-ecs-patterns

[spensireli]

Describe the issue

If I'm reading this correctly the desiredTaskCount isn't actually a property of queueProcessingEc2Service, so it cannot be specified as it is in the example.

Hi @spensireli , thanks for reporting this. I can confirm that its non existent in QueueProcessingEc2Service construct(QueueProcessingServiceBase).

I found this mention in ECS service where related desiredCount parameter is read from FLAG value to be passed to EC2 Service props.

aws-cdk/packages/aws-cdk-lib/aws-ecs-patterns/lib/ecs/queue-processing-ecs-service.ts

Line 132 in 7bb9203

const desiredCount = FeatureFlags.of(this).isEnabled(cxapi.ECS_REMOVE_DEFAULT_DESIRED_COUNT) ? undefined : this.desiredCount;

If i try to access it, the synth process would give error as its not in the props-

So this seems legit, Marking it as P3 as its a documentation bug, contributions from the community are welcome

Okay thought so, I'll try and find time to craft a PR.
